## Description

In SQLite 3.44.0 through 3.49.0 before 3.49.1, the concat_ws() SQL functioncan cause memory to be written beyond the end of a malloc-allocated buffer.If the separator argument is attacker-controlled and has a large string(e.g., 2MB or more), an integer overflow occurs in calculating the size ofthe result buffer, and thus malloc may not allocate enough memory.
